Hi everybody mbx-239 works well and vga output is ok but there is no image on screen (black screen) . Voltages that feed lcd manually wired but no action . I think lcd can not detect and my question is which one of pch or gpu is responsible for lcd detecting in this platform. (lcd_clk & lcd_dat) There is no schematic unfortunately. |

Edid clck and data and lvds goes from PCH. Try to press pch, or connect another lcd. And check voltages on lvds connector. |
